SLOW-RELEASE PEST CONTROL SYSTEM USING A POLYMER MATRIX CARRIER COMPRISING A VINYL POLYMER, A LIQUID PLASTICIZER FOR THE POLYMER AND TRIPHENYL PHOSPHATE AS A CARRIER FOR THE ACTIVE PESTICIDE

摘要

The invention relates to a solid pesticidal system which comprises a polymer matrix, a liquid plasticiser, a pesticidal active ingredient and triphenyl phosphate as vehicle for the active ingredient. The system efficiently and uniformly releases the active ingredient. The pesticidal system is less irritating for the skin of the animal than the systems of the prior art. The system is useful for manufacturing collars for animals, auricular plates, pesticidal strips and the like.
